King Cobra

The King Cobra is the world's longest venomous snake, with a length up to 5.6 m. This species is widespread throughout Southeast Asia and parts of India, and is found mostly in forested areas. The king cobra is fierce, agile and can produce large amounts of highly potent venom in a single bite. It is one of the most dangerous and feared Asiatic snakes.The venom of King Cobra is primarily neurotoxic but also contains cardiotoxic compounds.It is composed mostly of proteins and polypeptides. During a bite, venom is forced through the snake's half-inch (1.25 cm) fangs and into the wound, and quickly attacks the victim's central nervous system and induces severe pain, blurred vision, vertigo, drowsiness, and paralysis. Envenomation progresses to cardiovascular collapse, and the victim falls into a coma. Death soon follows due to respiratory failure. In the past, the LD50 of King Cobra’s venom was treated as 1.7 mg/kg (which is one of the least toxic elapids. However, this is not always true. According to the recent toxinology study, the LD50 of Chinese King Cobra venom is 0.34 mg/kg . This shows that actually King Cobra can be more venomous than most of the other species with its range, like chinese cobra]. The King Cobra is also capable of delivering larger quantities of venom than most other venomous snakes, injecting a 380-600 mg dose in a single bite. This quantity is enough to kill 20-40 grown men or even an elephant. One bite from a King Cobra can cause the death of a healthy adult human within 15 minutes,but death usually occurs between 30–45 minutes.The mortality rate from a bite can be over 75%, or only 33%, depending upon treatment details. It is regarded as one of the deadliest snakes in the world.
